To all whom it may concern:

Be it known that I, NAMAKA L. FAUFATA,

a citizen of the United States, residing at Paia, in the county of Mauiand Territory of Hawaii, have invented certain new and usefulImprovements in Railroad Applh ances, of which the followingis aspecification, reference being had to the accompanying drawings.

This invention relates to certain improve- .ments in railroad appliancesand has relaacter wherein the operating circuits therefor are undercontrol of a semaphore or the like and whereby said operating circuitscan be closed only when thelsemaphore or the like is at a predeterminedadpistment.

It is also a further object to providean appliance of this generalcharacter having novel and improved means whereby the operation of thebrakes of a train may be automatically set upon the train passing beyonda given point and whereby such means may be substantially automaticallyreset upon the release of the brake.

The invention consists in the details of construction and in thecombination and arrangement or the several parts of my improved railroadappliance whereby certain important advantagesare attained and thedevice is rendered simpler, less expensive and otherwise more convenientand advantageous for use, all aswill be hereinafter more fully setforth. c

The novel features of the invention will be carefully defined in theappended claim.

In order that my invention may be the better understood, 1 will nowproceed to describe the same with reference to the accompanying d1awings, wherein--.

Figure 1 is a diagrammatic view oi an ap pliance constructed inaccordance with an embodiment of my invention; Fig. 2v is an elevationalview, illustratin the means herein embodied for operating t e brakecontrolling means; Fig. 3 is a view in elevationof the mechanism hereinembodied for controlling the brake mechanism. a

As'disclosed in the accompanying -draw ings, 2 denotes a rail of atrackstructure, and 3 a semaphore disclosed in the accom v panyingdrawings as adjusted into a posi-" tion indicative o danger. Theoperation of this semaphore forms no part ofmy present Patented July e,1915.

invention and for this reason it is thought I that a detaileddescription thereof is unnec essary, other than to state that it isunder control ofthe semaphore rod 4 disposed upwardly within thestandard 5 and has afiixed thereto the contact 7 adapted to be in en-'gag'ement with the stationary contact 9, supported by the standard 5when the semaphore is in its tinned.

70, position hereinbefore men- The contacts 7 and 9- are electricallyconnected, as herein disclosed, through the medium of the conductor hand 2', respectively, with the brush 10 and the rail 2, the brush 10being positioned in close proximity to said rail 2 of the track-way. Thebrush l0 is adapted to be engaged by the shoe 11 carried by thelocomotive L and of a construc-.

tion and arrangement substantially identical as the shoe 11,hereinbe'fore referred to, and said shoe is electrically connectedthrough the medium of the conductor j with theelectromagnet E mountedupon the base 72, said base in actual practice being preferablypositioned within the cab of the locomotive.

The electromagnet E is also electrically connected with the rail 2through the mediumor" the conductor [a in a conventional man-' ner, and,as herein embodied, the conductor is has interposed therein the source Sor electrical energy. By this arrangement, it

will be seen that with the semaphore a position indicative of danger andthe s 00 11 in contact with the brush 10', the circuit thus closed willimpart movement to the armature A, said armature being herein disclosedas pivotally supported by the up standing arm 73 carried by the base 72and provided with the rock arm 7i which is operatively connected, as at75, with the 5 latch bar 76, the free extremity whereoi being adapted tocoact wit; the latch 7? carriedby the vertically movable member 78 tonormally hold such member 78 in an elevated position. As hereindisclosed, the

10 member 78 is slidably supported within the guide 79 carried by astandard 80 projecting upwardly from the base 72, and said upright 80 isalso provided with the upstanding arm Sl provided with a suitableopening 82 5 through which projects the bar 76 whereby said lever ismaintained in proper position.

The lower extremity of the arm 78 is operatively engaged with themovable contact I 83, and upon release of the member 78 such contact 83is caused to engage the stationary contact 84, and said contacts 83 and84 are electrically connected through the medium of the conductors Z andm, respectively, with the winding or coil JV, and the conductor m hasinterposed therein the source S of electrical energy, and when thewinding or coil circuitis closed, the core or solenoid 85 is caused toengage the pivoted latch member 86, carried by the handle 96, anddisengage the same from the handle lever 87, herein disclosed aspivotally engaged intermediate 'its'length with the standard 88projecting upwardly from the base 89, on which base the standard 90 ofthe coil or winding d is also secured; The outer extremity of the handlelever 87 has operatively engaged therewith through the medium of theadjustable hook member 91, one extremity of the retractable member 92herein shown as a 0 coil spring, the opposite or lower extremity of suchmember 92 being connected with the hook member 93 projecting upwardlyfrom the base 90. 'l he member 92 possesses such tension as to rock thelever 87 when released and cause the same to engage the upper extremityof the stem 94 of the check valve 95, whereby air is caused to dischargefrom the main line of the brake system and the brakes caused to be set.its the particular construction of the brake system forms no part o'fmyinvention, a detailed description or disclosure thereof is believed tobe unnecessary. I

. The handle 96 is pivotally engaged with the standard 88 and isnormally maintained in a horizontal position through the medium of thespring latch 97 operatively supported by the standard 98, and in orderto release the brakes, the latch 97 is disengaged (so through the mediumof the push rod 99 and the handle 96 moved upwardly until the latch 86engages "helever 87 and. whereupon the handle returned to its normalpost upward movement imparted to posed therein, a lev 2E Ur) through thestander l 88 and the conductor n with the stationary contact 196 withwhich is adapted to coact the movable co m tact 101 also carried by themember The movable contact 1.01 is electrically nected with theelectromagnet E thro" the medium of conductor o, magnet E is alsoelectrically cc in through the medium of th cond and (1 with the contact1612 gaged by the 163 the handle 96, and the co results in movementherein disclosed as pivotal termediate its length b t. projectingupwardly having its rear end provided L standing projection 10o to theprojection 196 by t e 78 whereby said memb engage the contacts 83, h

the member 78 th be operatt the bar 76, as believed to o parent to thoseskilled in my present invention appertainsa find it of advantage to havecon provided with the peripher i so that normally the circ magnet E isbroken. lntcrgiosed ductor n is the source S electrical on 78 beingsufiicient cause From the foregoing" descripti 00 thought to be obviousti Zr ance constructed in accor H. vention is of an extremely simpleparatively inexpensive nature ticularly well adanted .05

the convenience and faci may be assembled, it vious that my invention isso some change and modification rial departure from the pririci spiritthereof and for this reason do wish to be understood as limiting my theprecise arrangement and form. the'several parts herein shown in car outmy invention in practice.

I claim:

means for operating the circuit closer, and an additional electricallycontrolled means for returning the second named electrically controlledmeans to normal position, said last named electric means including acir- 1o cuit closer wherein one of the contacts is carried by the handlelever.

In testimony whereof I hereunto aflix my signature in the presence oftwo Witnesses. NAMAKA L. FAUFATA. Witnesses:
